Tungsten, a sintered composite consisting of at least one metal carbide. Tungsten-containing steels, such as high speed steels and some hot die steels, have a significant improvement in the hardness and heat resistance of steels, but the toughness will drop sharply.

Tungsten steel sintering molding, the first step is to pressed powder into blank, secondly put it into the sintering furnace heated to a certain temperature (sintering temperature), and keep a certain time (heat preservation time), and then cool down, so as to get the desired properties of tungsten steel materials.

Tungsten has widely use in many industry, such as: drilling tools, mining tools, measuring tools, wear-resistant parts, metal abrasive tools, cylinder lining, precision bearings, nozzle, etc.
